Abstract
There is provided bonding material having a Young's Modulus after hardening of not less than 20% of articles to be bonded, and an average linear coefficient of thermal expansion after hardening of not more than 70% of the articles to be bonded. This bonding material can suppress deformation of a honeycomb segment due to thermal stress to be generated by a bonding material layer and can suitably be used at the time of manufacturing exhaust gas trapping filters capable of reducing the generation of defects such as a crack, and above all, a diesel particulate filter (DPF) for trapping particulate matter (particulates) in exhaust gas from the diesel engine.
